The Engine Room: How Sparks and The Big Figure Built the Machine That Made Wilko Dangerous

There's a moment in almost every Dr. Feelgood performance where something clicks. Wilko Johnson is already prowling the stage like a man possessed, that Telecaster spitting out its staccato volleys, eyes wide and somewhere else entirely. But the reason it works — the reason it doesn't collapse into chaos — is happening behind him. John B. Sparks and The Big Figure are doing something that sounds deceptively simple and is, in fact, anything but.

We've spent decades celebrating Wilko's guitar playing, and rightly so. The man rewired British rock. But the Feelgood sound wasn't built by one person. It was built by three, and two of them rarely get the credit they deserve.

Restraint as a Radical Act

By the mid-1970s, British rock was in full excess mode. Drum kits had become architectural projects. Bass lines were wandering off on extended holidays. Progressive rock had convinced an entire generation that complexity was the same thing as depth.

Then Dr. Feelgood turned up from Canvey Island and did the opposite.

The Big Figure — born John Martin, a name that barely anyone uses — played drums the way a good bouncer works a door: firm, precise, no unnecessary movement, utterly in control. There were no Keith Moon theatrics here, no extended fills designed to announce his presence. What he offered instead was a locked-in, almost brutal economy of motion. Every hit counted. Every pause was deliberate. In an era of maximalism, that kind of restraint was genuinely revolutionary.

John B. Sparks on bass was cut from the same cloth. His lines were low-slung and purposeful, anchoring Wilko's angular riffing without ever trying to compete with it. Where other bassists of the period were chasing melodic complexity, Sparks was digging a trench and staying in it — and that trench was exactly what the music needed.

The Geometry of the Feelgood Sound

To understand why the rhythm section mattered so much, you have to understand what Wilko was actually doing with his guitar. His playing wasn't traditionally rhythmic in the way that, say, a funk guitarist would be. It was more percussive than melodic, more attack than sustain. Those stabbing, choppy riffs landed like jabs — sharp, angular, with spaces between them that felt almost confrontational.

For that approach to function, the band underneath needed to be immovable. If Sparks had been wandering harmonically, or if The Big Figure had been filling every gap, Wilko's guitar would have been fighting for space rather than commanding it. Instead, the rhythm section created a kind of locked grid — a tight, unyielding framework that gave those riffs room to breathe and bite simultaneously.

Listen to something like She Does It Right or Roxette and pay attention to what's happening below the guitar. The bass is sitting deep in the pocket, almost stubbornly so. The drums are pushing hard but never overreaching. Together, they create a tension that makes Wilko's playing feel urgent rather than chaotic. It's the musical equivalent of a coiled spring.

Pub Rock's Secret Weapon

The pub rock scene that spawned Dr. Feelgood was, by its nature, a back-to-basics movement. Small venues, no frills, direct communication with an audience. In that environment, a rhythm section that could lock down a groove and hold it for the duration of a sweaty Friday night set was worth its weight in gold.

Sparks and The Big Figure were absolutely built for that world. There's a physicality to their playing that's almost tangible on the live recordings — particularly on Stupidity, the 1976 live album that went to number one without a single. That record is a masterclass in ensemble playing. The rhythm section doesn't just support the songs; it drives them forward with a kind of relentless momentum that explains why Feelgood crowds were so consistently fervent.

Pub rock, for all its importance in British music history, often gets reduced to a footnote — the thing that happened before punk. But the Feelgood rhythm section deserves to be recognised as a genuine influence on what came after. When the punk bands started stripping everything back, they were, consciously or not, following a path that Sparks and The Big Figure had already walked.

The Interplay That Made It Special

What's often overlooked is the degree to which the three of them were listening to each other. Wilko's rhythm guitar was functioning partly as a percussive element, which meant his relationship with The Big Figure was unusually close — almost conversational. The drummer wasn't simply keeping time; he was responding to the guitar's rhythmic attack, creating a kind of call and response that gave the music its characteristic snap.

Sparks, meanwhile, was doing the crucial work of bridging the two. His bass lines connected Wilko's mid-range aggression to the low-end foundation of the drums, creating a coherent sonic picture from three very different personalities. It's a role that rarely gets discussed in glamorous terms, but without it the whole thing falls apart.

There's a reason that the Feelgood sound proved so difficult to replicate. Bands have tried — and some have come close — but the specific chemistry of that rhythm section, the way it responded to and amplified Wilko's playing, was genuinely unique. You can learn the guitar techniques. You can study the riffs. But that particular engine room took years to build.

Giving Credit Where It's Due

Wilko Johnson himself has always been generous in acknowledging his bandmates. In interviews over the years, he's been clear that Dr. Feelgood was a collective achievement, not a solo project with backing musicians. But the broader conversation about the band's legacy has tended to focus on the guitar and, to a slightly lesser extent, Lee Brilleaux's vocals and presence.

Sparks and The Big Figure deserve better. They were architects of something that changed British music, even if their names aren't the ones that appear on the posters.

Next time you put on Down by the Jetty or Malpractice, try an experiment. Focus entirely on the rhythm section for one song. Just listen to the bass and drums in isolation, the way a producer might. What you'll hear is two musicians operating at the absolute peak of their craft — controlled, purposeful, and utterly committed to the music rather than to themselves.

That, as much as anything Wilko did with his Telecaster, is what made Dr. Feelgood one of the greatest British bands of their era. The spotlight has always pointed at the guitarist. But the engine that drove the whole machine? That was built in the engine room.
